100% renewable targets will require power storage to manage flows on the net
Electrolysers utilise these intermittent power flows to produce H2 gas from water
H2 gas can be stored in large quantities underground and transported via existing gas pipelines
H2 vehicles recharge faster and are more durable than battery powered transport
Growing H2 demand in industrial processes will reduce costs and increase supply

The EHA welcomes the European Commission’s Communication “A sustainable future for transport: Towards an integrated, technology-led and user friendly system” (COM 2009/279/4) that was presented on June 17, 2009. The EHA fully supports the Commission’s reference to the need for the implementation of demontration projects and public interventions with regards to the development of infrastructure that supports new vehicles like “smart grids for electric transport or hydrogen distribution networks” (no. 79 in the document). However the EHA strongly suggests the use of the word “and” not “or” in this sentence as the development of electric transport in Europe will regard both battery powered as fuel cell powered vehicles, fuelled by hydrogen, to cover all transport needs. Battery car development will in fact further  enhance the production of commercial fuel cell vehicles. To achieve the EU’s objective of an “integrated, technology-led and user friendly system” the EHA refers to the need to confront the efficient use of primary energy, including renewables, to produce the  electricity to power battery cars and hydrogen to fuel cell vehicles. The EHA in collaboration with the German Hydrogen and Fuel Cell Association, DWV, and other national associations is preparing a paper to explain how an efficient and sustainable electric transport infrastructure to fuel both battery and fuel cell cars can be best achieved . A recent study of the US National Hydrogen Asscoation, reviewed by the US Department of Energy, demonstrates that 80% CO2 reduction in 2050 is only possible with the use of hydrogen in fuel cell cars (see under EU policy)
